Evan said that the difference between two negative numbers must be negative. Was he right? Use examples to illustrate your answe

vladimir1956 [14]

Yes he is right because if u have

-6 -(-4) u would multiply the 2 signs the - and the -4 and u would get +4

then ur equation becomes -6+4 = -2

A green die and a red die are tossed. What is the probability that a "4" shows on the green die and a "5" shows on the red die?

Vera_Pavlovna [14]

Answer:

1 out of 6 for green die and 1 out of 6 for red die

Step-by-step explanation:

As we know there are six numbers on both of the dices

so if we toss a die there is a 1 out of 6 outcomes that a 4 comes out for the green die and 1 out of 6 outcomes again for the red die

Which portion of the unit circle satisfies the trigonometric inequality cos^2theta + sin^2theta is greater than or equal to 1. A

liberstina [14]

Answer:

Only points on the circle satisfy the given inequality.

Step-by-step explanation:

Given: Unit circle

To find: portion of the unit circle which satisfies the trigonometric inequality $\sin ^2\theta +\cos ^2\theta \geq 1$

Solution:

In the given figure, OA = 1 unit (as radius of the unit circle equal to 1)

$\sin \theta$ = side opposite to $\theta$ /hypotenuse

$\cos \theta$ = side adjacent to $\theta$ /hypotenuse

$\sin \theta =\frac{AB}{AO}\\\sin \theta =\frac{AB}{1}\\AB=\sin \theta$

$\cos \theta=\frac{OB}{AO}\\\cos \theta =\frac{OB}{1}\\OB=\cos \theta$

So, coordinates of A = $\left ( \cos \theta ,\sin \theta \right )$

For any point (x,y) on the unit circle with centre at origin, equation of circle is given by $x^2+y^2=1$

Put $(x,y)=\left ( \cos \theta ,\sin \theta \right )$

$\cos ^2\theta +\sin ^2\theta =1$

So, $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ satisfies the equation $x^2+y^2=1$

For points $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ inside the circle, $\cos ^2\theta +\sin ^2\theta$

For points $(x,y)=\left ( \cos \theta ,\sin \theta \right )$ outside the circle, $\cos ^2\theta +\sin ^2\theta >1$

So, only points on the circle satisfy the given inequality.

John had $50 to spend at the mall. He purchased a shirt for $17.50, a pair of pants for $24.99, and a belt for $6.99. John used

Natasha2012 [34]

Answer:

John has 2 dollars and 46 cents left after his purchases.

Step-by-step explanation:

50 - 17.50 = 32.50

32.50 - 24.99 = 7.51

7.51 - 6.99 = 0.52

0.52 + 5.00 = 5.52

5.52 - 3.06 = 2.46

Contact [7]

Answer:

$y = \frac{1}{2}x +4$

Step-by-step explanation:

1. Find the slope of the line by plotting the points or by using the equation to find the slope.

2. Plot the line using the slope and find the y-intercept, which is 4.

3. Put your information together to get the equation $y = \frac{1}{2}x +4$ .
